Here are the blades of a 20 inch diameter turbine, that produces about half a kilowatt. They will be mounted on a shaft that projects for a long distance forward, and backward, at an angle from horizontal, so that the wind encounters the rotors like a stairway. Each additional rotor brings more power. The combined output from all these small rotors really adds up.

This Turbine Utilizes Massive Parallel Wind Processing (MPWP) to maximize the wattage generated for a turbine of a given diameter. The New Turbine is flown in Tehachapi, mounted to a Tower by Brent Scheibel, of General Electric Wind and owner of WindTesting.com. Power Inc. - Technology.

Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today.

Zero Energy Home Glows Green When it’s Good for the Planet. So often Prius owners are accused of being pious and smug – just wanting you to know how virtuous they are; by doing the right thing for the planet. This zero energy home takes that protest-too-much quality one step further: It advertises frankly to the neighbors when it is creating more energy than it is using. How? Energy efficient (LED of course) lights under the house glow eco-virtuous green when it is producing more than enough energy for its elegantly simple and spartan needs.

But what if the house is not making enough energy for its inhabitants? Well, when when it’s using more energy than it is making, this little house “blushes” an eco-embarrassed red. Wouldn’t that make your house next door feel just a little piggy? But, on the other hand; this has its good side. It’s not so hard to make your home an energy producer rather than an energy consumer. The south-facing side of the roof is almost half solar panels.
Renewable Energy Directory. Solar Panels Compared. What is the best solar cell you can buy?

It all depends on what is important to you. Two things that can be important are cost and size. For applications where space doesn't matter (like putting panels in your back yard or on your roof), you want to make the most power for the least cost. Here is what I've found... Solar Panels ranked by least cost per unit of power (best first) Clearly, large panels bought in bulk are more economical. For mobile applications (solar powered cell phone or lawn mower), you want the most power per unit of area. Solar Panels ranked by minimum size per unit of power (best first) Interestingly, some efficient panels are also economical.

"How to make a solar power generator". Using parts easily available from the internet (see helpful links) and your local stores, you can make a small solar power generator for $250 to $300.

Great for rolling blackouts, life outside the power grid, or the coming zombie apocalypse. Power your computer, modem, dvd, tv, cameras, lights, fans, or DC appliances anywhere you go. Use in cabins, boats, tents, archaeological digs, or while travelling throughout the third world. Have one in the office store room in case of power failures in your highrise.
Living Off the Grid: How to Generate Your Own Electricity. Our off the grid house near Anaconda, Montana Taking the Alternative Energy Plunge When my wife and I moved to Montana last year, we found a comfortable home on several acres with a view of the mountains.

There was only one hitch – the house was off the grid. In fact, everyone in the subdivision generated their own power, including the bed and breakfast nearby. That doesn’t mean it was primitive. Solar panel with tracker. How I built an electricity producing Solar Panel. Several years ago I bought some remote property in Arizona.

I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city light pollution, I found a great piece of remote property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. I built a wind turbine to provide some power on the remote property.
Plans for solar thermal, PV, Wind, Heating, Cooling, Cooking, and energy saving projects for Do It Yourselfers. Search The Renewable Energy site for Do-It-Yourselfers More than 500 renewable energy and conservation projects you can build.

This is the first time that a commercial development has integrated large-scale wind turbines within its design to harness the power of the wind. The three massive turbines, measuring 29 meters in diameter, are supported by bridges spanning between the complex's two towers. Through its positioning and the unique aerodynamic design of the towers, the prevailing on-shore Gulf breeze is funneled into the path of the turbines, helping to create power generation efficiency. Once operational, the wind turbines will deliver approximately 11-15% of the energy needs of the building, or 1100 to 1300 megawatt-hours per year -- enough to provide light in 300 homes for over a year.
Windbelt Micro-wind, 10 Times Cheaper Wind Energy!!
[Run time: 2:05 min] I hope you enjoy this short video of Shawn Frayne, a young inventor that has created this device to generate, on the micro-scale, energy for LED lights and radios in developing countries.

This is the first approach that uses aeroelastic flutter to create super cheap electricity.
The World’s First Energy-Generating Revolving Door. Harvesting the kinetic energy generated by crowds of people is one of our favorite approaches to renewable energy.

Recently Netherlands-based Natuurcafé La Port installed an energy generator in a rotating door, so every time someone walks in for a cup of coffee, they give just a little bit of their energy back to the coffee shop. We keep saying that solving the problem of global warming will require that we open up new doors in the field of renewable energy, but we must admit that we never expected to mean it literally!
Video. UK scientists invent artificial petrol - News Archive. Boffins at Rutherford Appleton Laboratory, near Oxford have invented an ‘artificial’ petrol, which costs just 90 pence per gallon and could run in existing cars. Motorists could even be able to drive for 300 to 400 miles before needing to fill up. The breakthrough comes as average UK fuel prices have hit a record high.
